This invention relates to a neck and closure structure of the typehaving a tubular neck and a removable closure for one end thereof. Moreparticularly, the invention relates to a neck and closure structure ofthis type where, for one reason. or another, a seal is desired orrequired between the neck and the 'closure, such as in the neck andclosure structures'of automobile radiators and automobile operatingmetal portions of obvious andin part will appear more in de-' otherreceptacle '2, or separate therefrom prov at its lower end with alateragasolinetanks. Heretofore, seals for such structures have been producedby annular gaskets of cork or! like material having the necessaryresiliency but with the disadvan- 'tage of being more or less rapidlydeteriorated if subjected to certain liquids or solutions, such assome'of the anti-freezing solutions put into automobile radiators in thewintertime. i 4 5 The general object of the present invention.

is the provision-of an improved neck and closure structure of thistype'whe'rein 00- t e neck and the closure provide the necessary ordesired'seal, so'that the easil deteriorative'cork gasket is, disensedwit wherein. simple and immeans is provided for enabling theclosure to be easily and quickly connected to and disconnected from theneck; and wherein the several partsare simple and inexpensive tomanufacture and convenient to assemble.

Further objects of the invention are in-part tail hereinafter.

In the accompanying drawings, Fig. l is a. central vertical sectionalview of a neck 3 and 4 are respectively a bottom plan viewand a topplanview of the closure of said structure. r- I e The neck of the presentstructure is a one piece sheet metal member and includes a tubular bodyportionlwhich may be an integral part of an automobile radiator, fueltank or vand suitably secured thereto around the open ing 3 thereof, thelatter arrangement being here shown with saidbody plortion provided yextending an- 1mm, or cmvnmun, omo, Assmuon no man m'rou n'xnn AND srnmecourm, or'cnnmm, 01:10, A conroiwrrou or one -member. Said body memberincludes'a top portion 15,.which-may be of dome shape, as

it to snugl surround the upper end portion and-the intermediate,verticall disposed an-\ nular connecting portion 12. aid upper inclinedortion 11 is the sealing portion of the neo and with the inner surfaceof said portion cooperates the sealing portion of the closure now to bedescribed.

The present closure com uses two sheet metal members, a body mem er anda sealing shown, 'and a depending cylindrical skirt rtion 17 having adiameter, which enables of the neo the binding ring 7 ofthe neck beingslightly compressed by said skirt portion and thereby serving tofrictionally main- Y tain the closure connected to the neck, as will bereadily understood. v Y

The closure sealing member has a top 50rtion 19 by meansof which it isconnect to the closure body member and a sealing portion 21 forcooperative engagement with the I sealing portion 11 of the neck. Intheresent embodiment of the invention, sai top portion 19 is anannularflange having its and closure sti'ucture embodying the present Iinvention; Fig. 2 is a centralvertical sectional outer. edge crimp'ed tothe closure body member at the junction of thetop and shit portionsthereof and the sealing portion 21 is an annular portion inclineddownwardl a'nd inwardly from the inner edge of said ange,

the inclination of said sealing rtion corresponding, of course, to theinclination of the sealing portion 11 of the neck.

The closure is removably secured to the neck by pressin the closuresln'rt portion 17 down around is e up r end of the -neck,

which causes the binding rin 7 of 'the neck to be compressed betweensaid clo'surefskirt portion and the groove wall parts 10, 11 and 1 2 ofthe neck body portion. Atthe same rtion,

time, the tapered closure sealing portion 21 enters the neck and firmlyengages the tapered neck sealing portion 11, thereby providing a tightseal between the closure and the neck. To remove the closure, it is onlynecessary to grasp the body member thereof and pull it from the neck,perhaps slightly twisting or rotating the closure relative to the neck,as will be readily understood.

If desired, and as shown, the closure sealing member may be providedwith a trans verse wall to close the air chamber 23 of the closure. Inthe present embodiment of the invention, said sealing member is providedwith a cup shaped extension, the cylindrical side portion 25 of which isof such size as to more or less snugly engage the neck portion 12 andthe circular bottom portion 27 of which serves as the bottom Wall of theair chamber 23. For venting purposes, said bot tom portion 27 isprovided with one or more openings 29 which establish communicationbetween the inside of the neck and hence the inside of the receptacle 2with the closure air chamber 23 and the top portion 15 of the closurebody member provided with one or more openings 30 which establishcommunication between the closure air chamber and the outsideatmosphere.

What I claim is:

1. A neck and closure structure, comprising a tubular neck and aremovable closure for one end thereof, said neck being provided withinits end to be closed with an annular metal sealing portion and saidclosure being provided with an annular metal sealing portion forcooperative engagement with the sealing portion of said neck, saidclosure being also provided with a depending skirt portion and said neckbeing provided exteriorly at its end to be closed with means forcooperation with said closure skirt portion to enable the closure to beremovably connected to the neck.

2. A neck and closure structure, comprising a tubular neck and aremovable closure for one end thereof, said neck being provided withinits end to be closed with an annular metal tapered sealing portion andsaid closure being provided with an annular metal tapered sealingportion for cooperative engagement with the sealing portion of saidneck, said closure being also provided with a depending skirt portionand said neck being provided exteriorly at its end to be closed withmeans for cooperation with said closure skirt portion to enable theclosure to be removably connected to the neck.

3. A neck and closure structure, comprising a tubular neck and aremovable closure for one end thereof, said neck being provided withinits end to be closed with an annular metal sealing portion and saidclosure being provided with an annular metal sealing pore tion forcooperative engagement with the sealing portion of said neck, saidclosure being also provided with a depending skirt portion and said neckbeing provided exteriorly at its end to be closed with a binding ringfor frictional securing engagement with said closure skirt portion,whereby said closure can be removably secured to sald neck.

4. A neck and closure structure, comprising a tubular neck and aremovable closure for one end thereof, said neck being provided withinits end to be closed with an annular metal tapered sealing portion andsaid closure being provided with an annular metal tapered-sealingportion for cooperative engagement with the sealing portion of saidneck, said closure being also provided with a depending skirt portionand said neck being provided exteriorly at its end to be closed with abinding ring for frictional securing 4 engagement with said closureskirt portion,
